Here, he studied the regulation of sleep and the human circadian rhythm. He and his students also analyzed the characteristics of sleep and the effects of chronic sleep deprivation. Together with one of his students, Dr. They determined that it was a regular phase of sleep that repeated four to five times in a normal night. REM was defined as a period of lighter sleep when patients most often had vivid dreams. Later, he went on to do more in-depth research on the relationship between REM sleep and dreams.
Because of his dedication to the field, Dement became one of the leading experts on sleep disorders and dreams. Following the work Kleitman and his students, there was rapid advancement within the field of sleep research. Here are some of the highlights:. Sleep research, in recent years, has grown to encompass many other fields — from cardiovascular research, neurology, otolaryngology and more.
The National Center for Sleep Disorders Research was created in to oversee the vast array of studies related to the diagnosis and treatment of sleep problems carried out every year. This governing body works to raise awareness about best practices and share information about new developments with professionals in the field of sleep research. The treatment options and equipment designed to help with sleep disorders continues to improve.
Research has shown that meditation, in combination with other healthy lifestyle habits, has the ability to help improve overall sleep quality by decreasing the amount of time it takes for you to fall asleep and decreasing the number of times you wake up in the night.
Certain forms of meditation also appear to distinctly enhance REM sleep 8 9. Meditation is also an important key to improving symptoms of high stress and persistent feelings of anxiousness — both of which can contribute to poor sleep patterns.
Depending on what are doing throughout the day and which phase of sleep we are in at night, our brain will predominantly exhibit certain brain wave patterns In both states, breath rate decreases, heart rate decreases, and blood pressure drops, among other physiological effects.
During meditation, we are getting into the alpha and theta brain waves—the same ones that occur in the earlier stages of our sleep cycle 8.
However, meditation is not a direct replacement for sleep, as meditation does not activate the deep sleep delta brain waves which are necessary for complete rest. Instead, meditation is a useful tool for improving the quality of nearly all stages of sleep. You can register HERE! United Kingdom. United States. Rest of Latin America and Caribbean.

While the first advances in sleep research date back to BC, the last century has delivered a steady drumbeat of groundbreaking discovery. Despite these advances, so much remains unknown. With rapidly evolving technology and increased accessibility to wearable and at-home sleep tracking capabilities, the next century of sleep research promises to shed new light on what happens to our brains after dark.
As we sleep, our mind travels through different phases, each of which contributes to sleep quality. Aug 18, Sleep Science Maggie Schlundt. Some of us get 8 hours of sleep and are still dragging, while some wake up feeling refreshed after less than 5 hours.
Long working days and regimented factory schedules including two shifts meant that people could no longer take a nap break whenever they wanted to.
Instead, for efficiency, they began compressing their shuteye into a single cycle. With the advent of publicly lit streets and electricity, urban residents further shifted away from a biphasic schedule. They also became more conscious of the passage of time and the productivity afforded during the waking state.
While biphasic sleep has been largely phased out from modern society, this schedule allows for more flexibility. Also, considering that people with sleep maintenance insomnia [4] may rest like this naturally, it could be beneficial for them to stop trying to fight a regimented monophasic schedule. Segmented rest is still prevalent in certain cultures [5] , such as Mediterranean, Hispanic, and Muslim communities.
Many work-related and family obligations require that individuals stay up later and rise at an hour that allows them to get to work on time. While some people have enough flexibility to adhere to a routine like this, they may find that biphasic sleeping leaves them with a feeling of sleep deprivation and fatigued.
In cases like this, a monophasic schedule is probably best for them. There are two types of biphasic sleep patterns. The first, commonly practiced during the 15th and 16th centuries, is when you go to sleep in the evening, wake up during the night for several hours, and fall back asleep. The second type is when you sleep at night and take a nap during the day and is usually caused by daytime sleepiness. Some human beings actively pursue a sleep pattern that includes more than two different sleep sessions.
This is known as polyphasic sleep. Some research suggests that this type of rest pattern may help reduce [6] the adverse effects of sleep deprivation.
